WILLIAM HINOHLIFFE, OF NASHVILLE, TENNESSEE.

IM PROVEMENT IN DOOR-SECI JRERS.

Specification forming part of Letters Patent No. 209,261, dated October22, 1878 application filed August 29, 1878.

.To all whom it may concern:

Be it known that I, WILLIAM HINGHLIBFE, of Nashville, in the county ofDavidson and State of Tennessee, have invented a new and ImprovedDoor-Fastenin g, of which the following is a specification:

Figure 1 is a front view of my improved fastening, shown as fasteningthe door closed. Fig. 2 is a side view of the same, shown as fasteningthe door partly open. Fig. 3 is a detail section taken through the'linew m, Fig. 2. Fig. 4 is a detail section taken through the line 3 y, Fig.1.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish an improved door-fastening,which shall be so constructed that it may be used to fasten the doorwhen closed and when partly open, and which shall be simple inconstruction and convenient and reliable in use.

The invention consists in the combination of the plate, the hingedstrap, the pivoted, notched, and flanged bar, and the flanged, slotted,and notched plate with each other to adapt them to be applied to adoor-casing and door, as hereinafter fully described.

A represents a door, and B a doorcasing. O is a plate, which is attachedto the casin g B, and to the inner edge of which is hinged a narrowstrap, D. To the strap D is pivoted,

by a rii et, the end of a bar, E, which has one or more notches formedin its lower edge, and the free end of which is bent over at rightaugles to form a flange. F is a plate attached to the door A, the rearend of which is bent outward, or has an outwardly projecting flangeformed upon it. The forward end of the plate F is bent outward and thenforward, or has an angular flange formed upon it. The flanges of theplate F are slotted from their upper edges and close to the body of thesaid plate F, to receive the bar E in fastening the door shut.

In the forwardly-projecting part of the for; ward flange of the plate Fis formed a T-notch to receive the hinge-strap D and the bar E. Themouth of the T-notch is made wide enough to allow the strap D to bepassed in and out through it, and the arms of the said notch are madedeep enough to allow the bar E to slide through them.

By this construction, by allowing the bar E to rest with either of itsnotches upon the edge of the plate F, at the end of the lower arm of theT-notch, the door will be fastened partly open, and cannot be moved ineither direction without first raising the said bar E.

When the door is closed, the bar E and strap D can beswung out of theTnotch and allowed to hang down along the door-casin g, as shown indotted lines in Fig. 1.

When the door is to be fastened shut, the bar E is swung around into theslots in the flanges of the plate F, as shown in Figs. 1 and 4.

If desired, the strap D may be made so wide that it will not passthrough the mouth of the T-notch in the flange of the plate F. In thiscase the inner part of the bar E must be notched or havea neck formedupon it of such a width that it will pass through the mouth of the saidT-notch when the door is fully closed.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- The combination of the plate 0, the hingedstrap D, the pivoted, notched, and flanged bar E, and the flanged,slotted, and notched plate F with each other to adapt them to be appliedto a door, substantially as herein shown and described.

WVILLIAM HINOHLIFFE.
